Q Designs is selling a unisex bracelet that doubles as a charging station for cellphones. Other products will follow, as part of an explosion in the $8 billion wearable-tech business.

The QBracelet, which can charge your cellphone, can be preordered for $99.

Charging a cellphone keeps getting easier and easier. The latest startup to enter the fray is Q Designs, a midtown west company selling a bracelet that doubles as both a fashion accessory and a charging station. The QBracelet is compatible with both Android and Apple devices, and can offer a charge of about 60% of battery life.

The QBracelet, now available for preorder from Qdesigns.co for $79, comes in black, silver or gold and is a unisex product. Q Designs, which was founded last year, received seed funding of $200,000 from an angel investor and micro venture capitalist fund. The firm eventually expects to roll out the bracelet to stores in the spring. Mr. Libani noted that other technologically useful products will be rolled out in the near future, but he did not offer specifics.

The fast-growing wearable-tech industry generated $8 billion in sales last year, a figure that is poised to reach $20 billion by 2017, according to Futuresource Consulting. Designers such as Tory Burch and Diane von Furstenberg have partnered with tech companies to launch their own wearable electronic products. In addition, Everpurse, a two-year-old Chicago-based company that sells a purse that charges phones, has already sold out of its flagship product. It’s now selling a mini version priced at $129. The company got its start through a Kickstarter campaign that netted more than $214,000 for the company.

The preorder-sales goal for the QBracelet is $50,000, according to Mr. Libani, who said the items should ship in time for the winter holidays. After the preorder period, the bracelets will retail for $99.
